models\weapons\w_models\w_nailgun.mdl - untextured models\weapons\w_models\w_nail.mdl - textured These two models suggest the presence of a nailgun intests of TF2. Having just discovered these I'm quite excited about the idea of this being re-introduced as one of those unlockable weapons. I never played the original TF, was there a nailgun in that? Something tells me its a demoman thing. Edit: just looked further and theres a lead pipe, a beartrap :O, branding Iron, dynamite and millions of grenades - Emp, healing, nail, gas..!
